Well, I left feedback as well, and I just got a call from the author.  He
mentioned that they had gotten 4 responses so far (seems low to me), but that
was an unheard of amount of reaction, usually they get none.  I brow beat him a
bit about some of the language used, but he seemed keen to cover the 3000 more
in the future.  I wouldn't be suprised if the others get phone calls as well.
